IMPROVEMENT IN IDETACHABLEV LINKS FORADRIVE-CHAVINS.

Specification forming part of Letters Patent' No. 219,126, dated September 2, 1879; application filedv .l une 13, 1879.

To all whom it may concern:

Be it known that I, LEVI W. STocKWELn, of Cleveland, in the county ot Cuyahoga and State ot' Ohio, have invented certain new and useful Improvements in Detachable Links for Drive-Chains, of which the following, in connection with the accompanying drawings, forming a parthereof, is a full, clear, and exact description.

In the drawings, Figure 1 is a plan view of a detachable drive-chain embodying my invention; Fig. 2, a section taken at the line a: Fig. y3, an edge viewV of two jointed links, and Fig. 4 a like representation.

Like letters of reference indicate like parts.

My invention has for its object the providing of certain novel andimproved means, sub-V stantially as hereinafter described, for the purpose of joinin g or articulating, detachabl y, the links of drive-chains.`

A A represent the links of a drive-chain, and B B are the end bars thereof. C is a coupling claspin g the end bars, which are'contiguous when the links are arranged together, the ends of the coupling being suciciently apart, as shown, to receive one end bar ata time, but adapted to hold both. D is a strip oi' ilexible sheet metal slipped between the contiguous end bars and the ends of the coupling, so as to close the same and confine the end bars therein, as shown. dicated in Fig. 1, hardly reaches the side bars ofthe links, while the ends of the dat or un-l 4 crimped sheet D extend a little way beyond The coupling, as in-` the inner edges of the side bars, when the latter lie horizontally or open, and both in the game plane, as indicated by that part of Fig. lnearest the left-hand margin of the drawing or sheet.

To crimp up the ends ot' the sheet D, so as to confine or hold all the parts together, it is only necessary to fold the links toward each other and against the sheet D, as indicated in Fig. 3. ln Fig. 4 the crimping process is represented as completed, as it also is in the right-hand portion of Fig. 1.

'It will now'be perceived that the crimped plate or sheet l) connects the links, so thatthey maybe turned freely in the coupling, and so that there is no danger ot' the links becoming separated accidentally. Yet they may be easily separated at will by pressing down the crimped ends of the sheet D, and then withdrawing it, as may easily be done by means of any simple tool adapted to that purpose.

Having thus described 1n y inventi0n what I claim as new, and desire to secure by Letters Patent, is i The combination, substantially as described, of the ilexiblecrimped sheet-metalplate D with the end bars and coupling of a detachable lrive-chain, substantially as and for the purposes specilied.
